Currently finishing industry, many companies still follow the tradition of large energy-consuming process, the process long and energy consumption. The transformation of traditional processes, promote the adoption of advanced energy-saving new technology, new technology, new equipment is to achieve the most effective way to save energy. According to local experience and information on domestic and foreign literature, the experts analyzed systematically organize for business information. Short pre-treatment and dyeing processes The desizing, scouring, bleaching of conventional three-step process of reform for the short process of desizing, scouring and bleaching efficiency steaming step process, this process is suitable for light syrup heteroatom little thin cotton fabric and polyester blends. Back steaming step and a half scouring and bleaching process, the first rolling back after the rolling base slurry reactor volume steaming liquid oxygen for one hour (100 ~ 102'C) efficient washing (stacked so that a step after the completion of a half step process), on a slurry liquid oxygen base cloth roll stacked on the light plasma light fabric by padding short base stacking. Efficient two-step process with short processes: one for the desizing + alkali oxygen one bath scouring and bleaching of the two-step process, that is, padding size roll back a dipping stacked high alkaline washing liquid oxygen Steaming ( 100 45? 60min) an efficient desizing reactor washing can also be rolled to a high efficiency washing liquid oxygen liquid alkali padding efficient steam (102 short steaming 2 ~ 4min) and efficient washing, this process is suitable for heavy syrup heavy fabric. There is also a cook for the withdrawal of a bath + conventional oxygen bleaching of the two-step process: the padding alkaline liquid oxygen and steam scouring agent 100 50 ~ 60 minutes, washing efficiency of conventional hydrogen peroxide bleaching of a dipping 50 to 100 steam 60 minutes efficient washing, this process is suitable for light syrup require a higher degree of thin white fabric. The above shortened process saves water, electricity, gas consumption 30% to 50%. Shortened pre-treatment process to promote new progress?? Enzyme oxygen alkali process: As the cotton fabric pre-treatment process, whether the traditional process, or the shortened process, should the use of caustic soda under high temperature surface activity chemical agents to complete tasks to complex, and a short cold pad-batch process technology, although this is low, but there are high concentrations of caustic soda. This process the wastewater produced by the more serious environmental pollution, for which countries have developed a bio-enzyme technology to replace traditional soda production process and the short process of alkali-oxygen process, into the 2l century, the first enzyme treatment process on the Application of progress rapidly and have achieved a lot, because the unique specificity of enzyme preparation, high efficiency, lower reaction conditions, biodegradable, water consumption and less easily washed away, to mixed results good. Environmentally friendly, low energy consumption, process and good quality short and has become the pre-treatment process of development, such as a printing and dyeing plant in Jiangsu using the first enzyme desizing, scouring after the enzyme and oxygen bleaching process, the effect is better, with the heap home a short time, processing time than the cold reactor technology to shorten more than 10 hours, lower cost (with less enzyme), desizing effect, in particular, greatly reduce water pollution, the COD value is lower than the traditional process to more than 10 times, particularly with pulp for high-density heavy weight cotton fabric pre-treatment, full compliance with clean production process, should be promoted. Cold pad-batch dyeing reactive dyes It is a semi-continuous dyeing process, ideal for small batch production of many varieties, large production flexibility, and energy saving significant dye, reactive dyes for cold pad demands for higher reactivity and hydrolysis stability, can be solid at room temperature to complete the color reaction, a higher fixation rate. According to the above conditions, B type reactive dyes fully applicable to the cold pad-batch dyeing cotton fabric in the dyeing, cold pad-batch process using a light-colored dye, good effect, but the dark, especially black, are made up less reactive requirements, and reactive dyes by Lei Masuo can address these problems. A wet wet process Mercerizing such as wet light, damp cloth with white agents, wet cloth on a damp cloth dyeing finishing agent, a drying process can be reduced to save energy, such as reactive short-flow steam of new technology (wet short steaming process), is the use of installed inside the entrance of steam in the reaction of far-infrared radiator, the stain soaking wet fabric after preheating, the fabric quickly warming up a small box by the reaction of steam and hot air mixture and heat 2 to 3 minutes solid color, so that reactive dyes to color rate, and full penetration, uniform color, according to the data indicate that reactive process of color yield rate of conventional steam curing process of the color yield than the conventional rate (the color yield rate Steam technology is only 70%), while the wet short steaming process color yield rate than conventional steaming process of the color yield rate of 10% to 20% by production practice, wet short steaming process did have a short fixed color rate, bright color and good reproducibility, energy saving, provincial dyes and so on.
